Wrong font size behaviour.

Create new note and write some text (let the font size to be 10pt). Now you want to change font size. It's ok if you select new font size from dropdown list. The other way to do this is to put cursor into font size field, delete "10" (press Delete twice), press 8 and then Enter. But after you press Delete first time VM will decrease font size to 1pt. After second Delete VM will delete your text at all.
